Act 2: Nightfall - 1. Inch by Inch

Move forward for a brief guide to your new commands. To be honest, I have never used them to much success, so forgive me if I never mention them.

Move up and swap the dead Hammer of Dawn for a shotgun. Forward is another fork in the road. I will advise going left. In the room ahead is a free crate so grab it quick. Get a Frag in hand.

The new enemy is called a Boomer. Take cover, and then blindfire a Frag in their direction. Your buddies up behind the Boomers will take care of them pretty well this time. Return fire if need be, but you shouldn't have to. Collect the Frags in the room behind you, go forward for a Y press, and then get the ammo if you need it.

*Up to you, but I took both Boomshots, swap the Gnasher.

In the statue room you will come under fire from a single guy out of the door. Just take cover and do whatever. There are Frags in this room and the next, but you don't need them, I think. Some press the button in the shelf room and go through. Turn right for some ammo and then leave the alley. Look up to the big opening straight ahead and up, be ready for the sniper. Then fire at the two Drones who pop up behind the fence, but make sure not to hit your guys who come from around the corner. Take cover and wait for two guys to rush outside. When they are gone, go the the other side of the opening and get a sight of the door. Run to the door and take out the Wretch(es) and the couple of guys. Then enter the other door in the hall and sneak up on the Troika gunner; he may sneak up on you.

Some Frags behind the gun and some ammo next to it. Go kick the door and wait around while your buddies exchange gossip. Proceed to the room with some steps. Go down and mantle the slab, cut up the couch, and grab COG #13. Go through the door.
